Steam regenerator
Thread Content
High-temperature steam is injected into this heat accumulator to heat the saturated water inside. As steam is introduced, both the temperature and pressure inside the container increase, but this happens while steam is being added. Should we consider the amount of steam that is introduced? I’ve always had this idea: the amount of steam introduced should be such that the water can absorb the heat from that steam; otherwise, if a large amount of steam remains inside, cavitation may occur, which could affect the equipment
There is a problem with your schematic diagram: steam enters the regenerator from below or from the sides, and beneath the liquid level, a distributor ensures that the steam comes into full contact with the saturated water, allowing them to mix together.
When using a steam regenerator, it is indeed necessary to consider the amount of steam to be charged. If a large amount of steam is introduced at once, the pressure inside the heat accumulator will increase sharply, which may pose safety hazards. Moreover, as you said, if the water has not yet absorbed all the heat from the steam, introducing a large amount of steam more could indeed lead to cavitation, which will affect the proper operation and service life of the equipment. Therefore, when introducing steam, we need to strictly control the amount of steam entering, and adjust the steam injection rate as appropriate based on the usage of the heat accumulator and the heat absorption by saturated water. If possible, it is best to install an automatic adjustment system to ensure the stable operation of the heat accumulator. .
No, steam enters the sleeve from the side or below to heat the water. But in this case, the temperature of the water is low at the beginning, and it’s in this way that inflation takes place; I’m not sure what purpose this process serves
This design is usually intended to improve thermal efficiency and protect the steam accumulator. At first, the water temperature is low, so the steam cannot be absorbed completely immediately. If it is introduced entirely from the top, it may exert significant pressure on the upper structure, and heat cannot be distributed evenly throughout the water body. When steam enters from the side or below, better heat exchange can be achieved; the heat from the steam can be distributed more evenly among the water, without causing excessive pressure or thermal stress on any particular part of the heat storage device. .
It was explained in too much detail; thanks for sharing, friend
